2 Player Arcade rain

[FullSpe3d98]

I searched for this and got nothing, so yeah.
I like racing against my little sister on 2 player a lot, but for some reason I can't choose any track which has Changing weather or time. There's just a red line through those tracks. For example I can play High Speed Ring but it won't let me play High Speed Ring /Change Weather. I thought I could unlock it at the end of the game but I have 96% game completion and level 40 A and B Spec. Can anyone help on this?

It's probably been disabled as it takes too much memory.

Weather is disabled in splitscreen due to performance issues.
The same reason that tire smoke, sparks, fireworks, and all other particle effects are disabled.

It surprised me that the game even had splitscreen at all.
